We are phasing out the following in tests:
add_dependencies - this is just kind of a clunky UI
require - normal JS requires cause test leaks
In order to plug require leaks, we are effectively doing what
we always have done inside of add_dependencies, which is to
keep track of which modules we have done `require` on, and
these get cleared between tests.
Now we just use `zrequire` every time we want to pull in real
code to our global namespace.
The node tests have purged modules from cache that were
included via things like set_global(), but calling require
directly would leak modules into the next test, which made
a couple tests only work when you ran the whole suite. I
fixed those tests to work standalone. And then I now make
dependencies explicitly clear the require cache before we
require them in namespace.js.
The with_overrides() function no longer works at the module
level, so you can temporarily override one function in a module
without breaking more permanent monkey patches.
This makes us slightly more vulnerable to unintentional test
leakages, but it solves the problem where you often need lots
of temporary overrides for writer functions but you want to
keep a more permanent override for some sort of reader function.
The function with_overrides() uses the logic from the old
run() function in dispatch.js to allow you to call a test
function and override parts of the global namespace only
for the duration of when test_function runs.
- Remove `underscore.js` from `static/third` and fetch it from `npm`.
- Upgrade `underscore.js` to 1.8.3.
- Bump up the `PROVISION_VERSION` to 4.2.
Part of #1709
We now sort lists of users ids deterministically, and we also
sort list of emails deterministically and without regard to case.
This probably fixes the bug #2343, although I never got a great
repro on that.
Some node tests used to pass as long as prior tests ran,
but then they would fail if you ran them standalone. Now
we are more aggressive about cleaning up node's require
cache after each individual test runs.
